[R-pkg-devel] no visible binding for '<<-' assignment note

I would guess that your NAMESPACE file doesn't export dnormfun.
Thank you Max.

The reason I used the super assignment  "<<-"  is because the "dnormfun" function later called by function kronecker(X, Y, FUN = "*",...) through FUN=" ". If I don't use the super assignment  "<<-"  then the kronecker function cannot find "dnormfun" function. The question now seems that how I can let the kronecker(X, Y, FUN = "*",...) know that "dnormfun" is a "FUN"?

Thanks,
Weimin

Hi Weimin,

From the R docs, if there is no visible binding for the deep assignment, meaning there is the variable "dnormfun" not already defined in the parent environment, then an assignment is made in the global assignment. Is this really what you want to do, define a function "dnormfun" that is available in the user's global environment? If yes, then you'll need to make a case for it in your CRAN submision comments. If no, then you can probably just change "<<-" to "<-".

Dear all,
In the last submission of my package the CRAN gave this note: "Check: R code for possible problems, Result: NOTE: no visible binding for '<<-' assignment..."

How can I bypass this note?

This is the local function which cause this note:
  dnormfun <<- function(muvalue, sigmavalue, aNumber = gridY[i] ){
    force(aNumber)
    ansvalue=dnorm(aNumber,muvalue,sqrt(sigmavalue))
    return(ansvalue)
  }

The package can run normally at my machine. Any suggestion?

Thanks,

Weimin
